First off, im an apple lover. i owned 2g,3g,3gs,3gs replacement X3 and now an iphone 4. I have bought my girlfriend all as well. including the iphone 4 at 399. I also own a brand new macbook pro.
i bought 2 iphone 4's the day they came out. Their is definitely an issue with holding it a certain way and it definitely affects me. It occurs on both of our phones..... The Bumper does not fix the issue for me at all and neither does some cheapo city case i bought yesterday. For me this position is very natural, I always hold my iphone in my left palm to text so its definitely affecting me when i am texting and surfing the web. It also affects me when i switch hands to hold the phone during a call to write or perform something with my right hand while i hold it in my left. Again, I can replicate it at anytime and it is definitely a natural position for me.
There is definitely alot of hype about this in the internet and the news but it should be. when something sells 600+ thousand items and theres an issue its going to happen. Im not complaining because i have been holding it different and using a headset to talk for the time being. I will wait patiently for a fix either software or hardware. Still absolutely love the phone.
And best of all, i like knowing i have 30 days to return it. even though i wont.
